I've taken the Halloween decorations down and am eager to fill baskets with gourds and Indian corn - my Thanksgiving totems. Tonight coming home on the bus I was one uncomfortable introvert caught between a young man and an older woman who were loudly and cheerfully debating the legalization of marijuana. He was for and she was against and they both had cogent and impassioned arguments.If the arguments had been written in an article, or intoned more quietly between acquaintances in a more private place - or if they had been part of a formalized debate I would have simply been mildly interested. But in the bus I felt accutely anxious. I am old fashioned I think, as well as introverted. Loud top of voice debate in a public place with a stranger feels wrong, off, vaguely dangerous - but both of the participants seemed to be enjoying the process, staying just a half step away from hostility. I was relieved when the bus got to my stop and I could escape into the cool quiet night.
